Because your garden variety unhealthy american who survives off fast food and takeout eats very, very little fiber. So they eat something with beans in it and they are totally unprepared for a significant amount of fiber.
I’ve also heard theories that because it’s already in little pieces people don’t chew it well, which also will upset your stomach.

If you don’t eat enough fiber-- which a lot of Americans do not do-- suddenly eating a lot of it will cause it to speed run through your system. Beans are high in fiber.
As far as burning shits, that’s just weakness to hot sauce.
